Advanced Metal 3D Printing with DMLS® Technology
At i3D MFG®, we harness cutting-edge Direct Metal Laser Solidification (DMLS®) technology to deliver high-performance, production-grade metal parts that meet the most demanding requirements. Our fleet of DMLS systems enables unparalleled precision, design freedom, and efficiency for industries where performance, speed, and complexity matter.
Core Capabilities
Our core capabilities span the full spectrum of metal additive manufacturing— from initial design optimization and rapid prototyping through precision DMLS® printing and comprehensive post processing. Backed by AS9100D-certified quality systems and in-house DFAM expertise, we deliver end-to-end solutions that accelerate time-to-market and ensure consistent, high-performance results.
Complex Geometries, No Compromises
DMLS eliminates the design constraints of traditional machining and casting. We manufacture fully functional metal components with complex internal channels, free-form surfaces, lattice structures, honeycombs, and conformal cooling pathways—no tooling, CNC programming, or post-fixture setup required.
Production-Ready Precision
From prototypes to production, we deliver repeatable, high-quality results with:
- Feature resolution down to 0.015″ (0.38 mm)
- Wall thickness as low as 0.012″ (0.3 mm)
- Layer thickness options of 20 or 40 microns
- Tolerances of ±0.005″ on first articles, ±0.002″ thereafter
Build Volumes for Every Need
Our equipment supports multiple build sizes to fit various project scopes—from intricate components to large-format parts:
- Small to medium: ~228 × 228 × 190 mm to 250 x 250 × 300 mm
- Large-format: up to 400 × 400 × 400 mm
This scalability allows clients to iterate quickly, consolidate assemblies, or scale production efficiently.
Lightweighting & Structural Optimization
We help customers reduce component weight by up to 70% using latticed, honeycombed, and topology optimized designs—all without compromising strength or function.
Rapid Turnaround & Seamless File Support
Our streamlined workflow supports rapid prototyping and production, with lead times as short as hours or days. We work directly with Solidworks, .STEP, and raw CAD files, enabling fast, tool-free manufacturing cycles.

Capability Constraints
At i3D, we help customers understand and design around these constraints to maximize the value of DMLS. By integrating smart engineering, process simulation, and expert postprocessing, we ensure your parts are optimized for performance and manufacturability.
1. Support Structures and Build Orientation
- Complex geometries often require support structures during printing, especially for overhangs greater than ~45°.
- Support removal can impact surface finish and increase post-processing time.
- As-printed surfaces typically have a rough finish (Ra 8–20 µm), depending on the material and build parameters.
- Additional post-processing such as machining, polishing, or shot peening is often required to meet tight surface
specifications.
2. Part Size Limitations
- Build volumes are restricted by the printer model (e.g., max ~400 × 400 × 400 mm)
- Larger parts may require segmentation and assembly after printing.
3. Material Availability
- DMLS supports a wide range of metals, but not all alloys can be printed.
- Material properties may vary from wrought equivalents, and custom alloy qualification can be time-consuming
and costly.
4. Thermal Stress and Warping
- Rapid heating and cooling can cause residual stresses, distortion, or cracking—especially in thin-walled or large
parts. - Proper design for additive manufacturing (DfAM) and simulation helps mitigate these risks.
5. Cost Considerations
- While DMLS reduces tooling and enables complex parts, the cost per part may be higher than traditional
manufacturing for large production volumes. - Best suited for low- to mid-volume production, high-complexity parts, or parts where performance justifies the
cost.
6. Powder Handling and Safety
- Metal powders require controlled handling environments due to flammability and inhalation risks.
- i3D follows strict safety and quality protocols for powder storage, reuse, and disposal.
